- In "The Hundredth Smurf" (third story in the "The Egg and the Smurfs" album), a hundred Smurfs are required for the Dance of the Moon, but there are 99 only. In "The Wild Smurf", we find that the Delivery Stork lost a Smurf who ended being the eponymous character. This means that if Wild Smurf didn't have get lost, they would have been 100 Smurfs! It fits!
- Rewatching some episodes (due to a case of nostalgia triggered by the release of the movie) with TV Tropes fresh on the brain reveals that this show is no more nor less Communist than most shows of the 80s.
- In The Movie, when the Smurfs go to an antique book shop to get the remaining elements of the potion required to go back to their world, they come across a book about their species. One of the pages from the original books shown during this scene comes from the book "The Smurf Apprentice", in which a Smurf tries his hand at magic. In the cartoon adaption of The Smurf Apprentice, Clumsy Smurf himself takes the role of the apprentice smurf. Now, who is one of the main Smurfs in the movie?
- Being quite young when first reading The Smurfs and the Howlibird, I understood one plot point way later: the reason why Papa Smurf tasked two Smurfs to get rid of his dangerous fertilizer formula "in the desert". Since it was shown to create Smurf-Eating Plants, Papa Smurf wanted it to be lost in a place with no plant life to avoid any risk of a repeat.
- The Movie sheds some light on Gargamel's entire motivation for capturing Smurfs - their skin flakes, sweat and tears carry potent magic, and a sample of Smurfette's hair allows him to power his ring and a wand. Surely the Smurfs can reach a compromise, like Gargamel leaving their village alone in exchange for weekly bags of shavings and hair clippings, toenail clippings and even tubs of bathwater...
- To be fair, Gargamel has the Villain Ball super glued to his hands.
- More importantly, it is a standard principle of magic that things like your hair, nail clippings, etc. can be used against you if a suitably evil magician were to get his or her hands on them. Very likely the Smurfs would be extremely wary of voluntarily giving those things to Gargamel, who fits the profile of "evil magician" to a "T".
- Not to mention the movie states that just a tiny portion of Smurfs essence has made Gargamel a serious threat to the Smurfs. If the Smurfs were to give him their hair, and such things that were extracted from Papa Smurf in the movie, Gargamel would go to next step... and try to (of course) take over the world. Or at least, the known world at that time.
- Also, Gargamel really wants the magic to himself with no regulations. Bargaining with the Smurfs and depending on them giving him hair and stuff would limit the convenience of just having it whenever he wants. That combined with the fact that giving Gargamel that stuff would give him an upper hand, and its easy to see that neither side would benefit much from this agreement.
- If you think about it, the naming and talents of Smurfs is actually pretty smurfed up. So, there are several hard-working smurfs. However, in the village, the majority has talents which screw up their lives (Lazy is almost constantly sleepy, but forced to work; Flighty can't decide on anything), or screw up the lives of the rest (Jokey, while being the morale booster, can get a little annoying, and, obviously, Clumsy). Both categories can end up ostracized by their society, in the case of Brainy, whose talent is implied not to be a know-it-all but to be a scapegoat. (And he's even more of a narcissist than Vanity is.) Think about it.
- How can Gargamel's books state that Smurf essence is needed to brew the Philosopher's Stone? Is this just theoretical alchémy or is it empirical? In the latter case, that would mean that, at some point in the past, some unnamed Smurf was boiled alive by an alchemist.
- In The Smurfs and the Howlibird, Papa Smurf's failed fertiliser turns a flower into a carnivorous plant. Then, it is accidentally ingested by a fledging bird, turning it into a big predatory bird overnight. What happened to the two other nestlings??
- In "Romeo and Smurfette", all the male Smurfs fall in love with Smurfette. This includes Papa Smurf, and if he's the father of everybody, then that would mean Smurfette was being hit on by her brothers.
